MADISON DALLAS, OF NEW ORLEANS, LOUISIANA.

CAN-OPENER.

SPECIFICATION forming part of Letters Patent No. 521,643, dated June 19,1894.

- Application filed October 31, 1893. Serial No. 489,649. (No model.)

To aZZ whom it may concern:

Be it known that I, MADISON DALLAS, a citizen of the United States,residing at New Orleans, in theparish of Orleans and State of-Louisiana, have invented new and useful Improvements in Gan-Openers, ofwhich the following is a specification.

This invention relates to that class of canopeners which are designedfor the purpose of cutting circular openings in the heads of cans, suchas are used for containing condensed milk, fruit or edibles of Variouskinds; and it consists of a circular cover, either flat or dome-shaped,as may be preferred, an annular ring of less diameter than the coversecured to' the under surface of same, a downwardly projectingcutting-blade connected with the aforesaid ring, and a handle with pinprojecting downwardly through the cover, as hereinafter more fullydescribed.

My invention is fully illustrated in the accompanying drawings, wherein-Figure 1 is a perspective View of the device Fig. 2 represents thehandle with its downward projection, and Fig. 3 is a verticalcross-section of the device applied as a cover, over an opening formedin the top of a can and near the edge thereof.

In the drawings, the letter A designates the cover, or body of mydevice, B a ring which is soldered, or otherwise secured to the underside of same, and O a cutting blade, connected with the aforesaid ringin any desired manner.

D, designates the handle, which is preferably made of stout wire bentinto oblong form with a downwardly-projecting pointed end,

- as shown at e. This end is made to penetrate the cover and thus form apivotal point to the device 5 the lower horizontal portion (f) of thehandle being soldered or otherwise secured to the upper surface of thecover, or within a groove formed therein, as shown at h, in Figs. ,7

1 and 3.

The diameter of the device is slightly less than that of the top of anordinary one pound can, so that it may be used for removing nearly theentire top of sucha can, or for cutting a similar sized opening inlarger cans.

In the operation of my invention it is only necessary to pierce the topof the can to be opened, and to press the device downward until itscutting blade shall have entered into the material of which theaforesaid top of can is composed, the device is then given one full turnin the direction of the cutting edge of the blade, thereby separatingfrom the cantop, a certain section thereof; the detached section is thenremoved by means of the pivotal portion of the device, and the openingclosed by applying said device, as shown at Fig. 3.

I do not desire to limit myself to the exact form, or proportion of thedevice herein described, but I What I do claim as new, and desire tosecure by Letters Patent, is-

The herein described can-opener, consisting of a cover the under surfaceof which is provided with an annular ring having a cutting-bladeconnected with the outer side thereof, a handle secured to the top ofthe cover, and a pin projecting downwardlyfrom said handle and throughthe top of the cover, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in the presence of twowitnesses.

MADISON DALLAS.
